Electrostatic Interactions

Definition

Electrostatic interactions are forces that occur between charged particles, which can be either attractive or repulsive depending on the types of charges involved. These interactions play a crucial role in determining the behavior of molecular and nanostructures, influencing how they organize and interact with each other. In the context of small-scale materials, these forces can dictate self-assembly processes, stability in device integration, and the effectiveness of template-directed synthesis.
